"THE LEGEND OF THE SHAMROCK"
"Long ago in Ireland, St. Patrick looked around and noticed tiny shamrocks covering the ground...picking one up, he studied it and realized what the three leaves of the shamrock might symbolize...
One leaf to show the Father, One leaf to show the Son, One leaf to show the Holy Ghost, the blessed Three-in-One...
And that's the way the shamrock of Ireland came to be.  A symbol to remind us of the Holy Trinity."
